Electrolytic copper foil diaphanous spot of the present utility model also is in the design feature of level detecting apparatus:
Described display is LCD display.
Described image pick-up card comprises video input interface, A/D converter and video output interface; Described two ccd video cameras comprise the first ccd video camera and the second ccd video camera; Described the first ccd video camera all is connected with described video input interface with the second ccd video camera, described video input interface is connected with described A/D converter, described A/D converter is connected with described video output interface, and described video output interface is connected with described control computing machine.
Compared with the prior art, the utility model beneficial effect is embodied in:
Adopt two ccd video cameras, carry out image by binocular vision in conjunction with present technique and process, solve a Copper Foil difficult problem that is difficult to detect in place that contains reduced size (below 15 microns) diaphanous spot.And adopt this technology can well realize detecting online originally to only have the user to adopt the seep through mode just can detectable pin hole, can satisfy the requirement of batch production detection in place, be conducive to enhance productivity, reduce material and labor cost, can solve the difficult problem that the traditional detection mode can not realize detection in place and can cause waste of raw materials, also be beneficial to the reduction cost, increase product percent of pass.Electrolytic copper foil diaphanous spot of the present utility model is at level detecting apparatus, and the pin hole characteristics of image is obvious after processing, and has the coordinate take reference point as initial point to show; Can reduce original detection difficulty, improve accuracy of detection, reliable and stable; Reduce cost, reduce seep through and detect the waste that causes; In time pinpoint the problems, can not contain diaphanous spot Copper Foil continuation production because causing after the problem discover; Highly versatile is applicable to all Copper Foil production fields, and product operation is simple.
Electrolytic copper foil diaphanous spot of the present utility model is at level detecting apparatus, have can be online to the pin hole of Copper Foil detect accurately, testing cost is low, improved the advantages such as product quality of Copper Foil.
Description of drawings
Fig. 1 is that electrolytic copper foil diaphanous spot of the present utility model is at the structural drawing of level detecting apparatus.
Fig. 2 is the Copper Foil image of electrolytic copper foil diaphanous spot of the present utility model before and after the processing of level detecting apparatus.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment
Referring to accompanying drawing 1, the electrolytic copper foil diaphanous spot comprises control computing machine, two ccd video cameras, image pick-up card, display and supervisory keyboards at level detecting apparatus; Each ccd video camera in described two ccd video cameras all is connected with image pick-up card, and described image pick-up card is connected with described control computing machine; Described control computing machine also is provided with described display and supervisory keyboard.
Described display is LCD display.
Described image pick-up card comprises video input interface, A/D converter and video output interface; Described two ccd video cameras comprise the first ccd video camera and the second ccd video camera; Described the first ccd video camera all is connected with described video input interface with the second ccd video camera, described video input interface is connected with described A/D converter, described A/D converter is connected with described video output interface, and described video output interface is connected with described control computing machine.
By ccd video camera the Copper Foil on the production line is carried out video capture, and the video of taking is transferred to image pick-up card in real time, by image pick-up card to obtain the video data of ccd video camera transmission by video input interface, then the screen data are carried out digital-to-analog conversion, and the screen data communication device after the digital-to-analog conversion is crossed video output interface be transferred to the control computing machine.The staff operates whole system by supervisory keyboard, and by supervisory keyboard input control parameter.The image that shows Copper Foil at display, the pin hole of Copper Foil are also simultaneously at display shown (as shown in Figure 2).
